The side of a rhombus is 15 centimeters long, and the length of its longer diagonal is 24.6 centimeters. Find the area.

The diagonals in a rhombus rightbisect each other, giving you 4 identical rightangled triangles
look at one of them, the hypotenuse would be 15 and the other side is 12.3 , half the diagonal given.
Can you find the missing side using Pythagoras?
